Çokluk, Ömay; Gül, Emrah; Dogan-Gül, Çilem – Educational Sciences: Theory and Practice, 2016
The study aims to examine whether differential item function is displayed in three different test forms that have item orders of random and sequential versions (easy-to-hard and hard-to-easy), based on Classical Test Theory (CTT) and Item Response Theory (IRT) methods and bearing item difficulty levels in mind. In the correlational research, the…
